Honestly, you can't sell yourself as a burger expert if you think 5 Guys "kills it". Five Guys is good, but it should not be a destination burger place. It's a place that you go if you want a burger better than fast food and not as good as most of the places mentioned on this list. Btw, last time I was at Flip, it was ten times better than any burger I've ever had at Five Guys, and I've had a lot of them.
As far as Shake Shake goes, this reminds me of the In-N-Out hype. I was told repeatedly how great it was, finally went to one with high expectations. Left feeling just like those who write that Shake Shack is just a step above Wendy's.
